2016 - PRESENTEos Analytics/Eos HealthCheck- Created an app, back-end, and dashboard allowing doctors to have their patients complete various health checks much more quickly and without paper forms.
- Built a serverless HTTP API over MongoDB which is fully compatible with CouchDB's replication API and algorithm, so that a MongoDB backend can synchronize with PouchDB clients or other CouchDB servers while utilizing API Gateway's flexible power for authentication and traffic management.
- Created integrations between our back-end and various data providers (weather, census data, electoral records) to provide a unified REST API for information about a local area.
- Responsible for designing and building data security policies and systems both technically and legally, in the particularly sensitive medical domain.
- Worked closely with medical professionals and administrators to design efficient processes and clear interfaces.

2009 - 2012Trinity College, Cambridge University- Built a platform to host modular web apps performing various functions for staff and students.
- Introduced REST APIs and SPA-style modules in ExtJS to improve responsiveness and implement feature-rich UI components, such as editable data tabes.
- Redesigned the central database of staff, students and alumni to be built directly from SQL views, rather than batch update jobs or manual input.
- Devised and built a new system for immediate verification and registration of college guests onto the academic wifi network, using a web app calling firewall APIs for IP allocation. This replaced a paper application form and manual process.
- Transitioned a shared hosting setup for college fellow and society pages to a new vhost-based setup, segregating the filesystem and hosting options for security and allowing more features to be enabled.

The most amazing...
...app I've built was as co-founder of Eos. We connected patients with their doctors for easier and cheaper health checks, helping detect and prevent illnesses.
Employment
Experience
- Eos HealthCheck (Development)
A patient-facing mobile app, clinician-facing web app and secure backend to provide various primary care services through a more user-friendly and less time intensive means.
Allows patients to order home blood tests, answer questions from their GP, maintain a diary of their conditions and treatments, and be recommended with a face-to-face consultation where appropriate.
HealthCheck is currently being piloted with GPs in London. - Open Source Packages via NPM (Other amazing things)https://www.npmjs.com/~rh389
I have built and maintain a range of open source packages.
Some of my most popular libraries are:
react-native-securerandom - Wraps native libraries allowing React Native developers to build apps in highly security-sensitive domains.
dynamodb-geo - Leverages S2 to add location-based indexing to AWS DynamoDB tables.
react-native-paho-mqtt - Allows React Native developers to build connected apps around MQTT messaging, as common in "internet of things" products.
